CUFF BUTTON.

Application filed May 9, 1925. Serial No. 29,067.

To al! autom. if 112:52/ mice/'itx Be it known that l, JoirN G. Nrnmie, a 'itizen of the United States, residing at Providence, in the county ot Providence and State ot Rhode island, have invented certain new and useful lmproven'ients in Culi Buttons, ot' which the following is a speciication.

This invention relates to an improved construction of culi buttons ot the separable type, and has for its objectl to provide a button of this character comprising stud and socket members, the stud member carrying separable aws to releasably enjiae the socket member and this stud membci 'lso provided with an axially movable p1 o erablc through its outer head tor controlling` the engaging and releasing actions or the jaw members with the socket member,

A further object ot this invention is the provision of a pair` ot jaws in the stud member, each having an inwardly extending lip tor engagement with an axially movable pin, the pin being` recessed for the reception oi the lips of the jaw members to permit the jaws to move toward each other to released position.

A further object of this invention is to provide a spring acting `upon the jaw members Jfor moving thesemembers toward each other when permitted by axial movement of the controlpin.

lith these and other objects in view, the invention consists of certain novel features et construction, as will be more 'fully described, and particularly pointed out in the appended claims.

In the accompanying' drawings,

Figure l is a side elevation partly in section illustrating the stud and socket members of av cuil button as locked together.

Figure 2 is a perspective View of one of the jaw members.

Figure 3 is a plan view illustrating the spring for moving the jaw members toward each other.

Figure 4e is a sectional view illustrating the spring in its operative position in relation to the jaw members.

Figure 5 is a side elevation partly in section illustrating the jaw members in releasing position.

Figure 6 is a sectional plan view taken on line 6-6 of Figure 5.

' these ad lt is onnd in thc practical operation and construction of cuil" buttons, oi' advantage to provide readily operable means whereby the button members are positively locked together so that they cannot be separated except by manual manipulation of a central pin; and te accomplish this object, I have provided laterally movable jaws in the stud acefl upon by a spring for moving tws toward each other to contracted in which position thev are adapted through the opening in the socket and l have provided an axially fle pin operable through the head of ie .stud member tor spreading the aw mei bers into expanded gripping position anu controlling the action ot' these jaw members; and the following is a detailed deseriptimi of the present embodiment of this invention showing one construction by which .tage-ous results may be accomplished lVith reference to the drawings, 10 designates the stud member and ll the socket member ot the separable button, the socket member being provided with an outer head l2 and an inner head 13, the inner head being provided with a plate lilhaving a central opening 'l5 for the reception of projecting locking jaws 16 mounted in the studl member l0. rlhe stud member is provided with an outer head 17 and an inner head 18, the inner head being provided with a plate 19 having an opening 2O therein. rFlirough this opening project the pair of jaws 1G flanged as at 22 and enlarged as at 23 to prevent them from being dislodged from the opening 20. Each of the jawsv is provided with an inwardly-extending lip 24C and an opening 25 for the reception of the ends 26 of an arcuate spring 27, which spring tends at all times to move the jaws toward each other into the position shown in Figures 4f, 5 and (i. able pin 28 extends between the jaws 16 normally in engagement with the inwardlyprojecting lip 24e and serving to spread the jaws into locking position, as illustrated in Figure l, and in order to permit the jaws to move to released position, the pin is recessed as at 29 so that an inward movement of the pin causes the recess to cooperate with the inwardly extending lips 24. to permit them to move toward each other An axially movunder the action of spring 27 into the position shown in Figure 5. rlhe outer end of the pin extends up into the presser cap 30 and is held in extended position through action of spring 3l, which forces the pin 28 outwardly to spread the jaws 16 into locking position. lt will be readily apparent that upon movement oi' cap 30 inwardly the jaws will be permitted to move to contracted position under action of spring 27 and permit their free insertion or renewal into the soclet member, and that when released the jaws will be expanded by the pin 2S into locking position.

My in 'iproved 'orm of separable button is very simple and effective in construction and attractive in its appearance, and by its use the button members may be positively locked against inadvertent separation and may be released to separate only by pressure upon the presser cap which extends through the outer head of one cf the button members.

The foregoing description is directed solely towards the construction illustrated, but l desire it to be understood, that reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

l. claim:

l. A separable cuit button comprising stud and socket members, separable bodily movable jaws carried by said stud member for releasably engaging said socket member, means for positively forcing said jaws to contracted position, an axially movable pin in said stud member for controlling the action ot' said jaws, and means acting on said pin for causing saidr pin to normally expand said jaws into their locking position.

2. A separable cuil button comprising stud and socket members, separable jaws carried by said stud member for releasably engaging said socket member, an axially slidable pin between said jaws and cooperating projection and recess means between said pin and jaws for moving said jaws to engaging position and permitting said jaws to move to released position upon different axial position of said pin.

3. A. separable cuil button comprising stud and socket members, separable jawS carried by said stud member for releasably engaging said socket member, an inwardlyextending projection on said jaws, a spring engaging said jaws for moving them toward each other into contracted released position, an axially movable spring pressed pin extending between said jaw in engagement with said projection 'for holding said jaws in expanded gripping position, said pin being provided with a recess for receiving said jaw projections to permit said jaws to more toward each other into released position.

el. A separable cuff button comprising stud and socliet members, a pair of bodily movable jaws in said stud member for ensaid socket member, each having an in.vardlyextending projection, an annularly-recessed pin extending between said jaws engaging said projection to spread said jaws into engagement with the walls of said socket and axially movable to permit said projections to extend into said recess and said jaws move toward each other to contracted released position.

5. A separable culi button comprising stud and soclret members, separable jaws carried by said stud member for releasably engaging said socket member, an arcuate spring having engagement with said jaws substa itially at diametrically opposite points for moving said jaws toward each other to released position, and an axially movable pin between said jaws .for controlling their action.

In testimony whereof l aiiix my signature.

JOHN G. NYBERG.
